As horizontal transistor gets very hot so no eht so no raster &no sound due to nosupply to vif & tuner. as hor output is getting hot please isolate supply to hor. section & check power supply output is ok as due to high voltage h/outout may get hot & demaged. if supply is ok check for leaky or short parts in hor output. 1 hor. output transistor itself if it is replaced that may not be of proper matching. 2 diode& cap.in eht section. 3 clean print near eht. 4 moisture near yoke due to rain in rainy season only. so keep it hot for few hours. 5 at last if all are ok eht or fly back transformer. re connect power to hor output after rectification
